Responding to Matt Riddell, M Shokuie, A J Stiles, and Telium Support (all below)
Thanks for the suggestions, but a separate gateway is a problem in the design as the configuration is basically: Carrier --- PRI --- Asterisk (with failover) ---- Legacy PBX | - SIP / IAX2 -- our service or remote office As this is already acting as a gateway adding another box to the mix seems a bit over kill (unless I can embed it and the asterisk PBX into a 2 U pizza box). But since most gateways are designed to be used for fail over servers / PBXs not lines I am not sure that this would benefit us. So far I have found 1 company that seems to have a gateway card and that is the beroNet PCI / PCIe Gateway Cards which they say has the card level failover. I will update the list should this meet the use case.
